If you have a question about this talk, please contact Andrew Thomason .

For a family A in {0,...,k}^n, its deletion shadow is the set obtained from A by deleting from any of its vectors one coordinate. Given the size of A, how should we choose A to minimise its deletion shadow? And what happens if instead we may delete only a coordinate that is zero? We discuss these problems, and give an exact solution to the second problem.
